First of all thanks Mum for keeping everyone up to date and thank you for all the comments and wishes.
Surgery went well, not too many gallstones, but a few large ones; so glad I have had it out. The hospital staff were wonderful and I could easily have stayed in for a couple of days - but modern medicine gets you up and out. Came home yesterday at 1pm, the dressing covering my drain site, overfilled so had to get it re-dressed last night, all well now.
Have woken feeling much better, still a little bruised and tender, but the nausea from yesterday has eased. Now I am taking everyone's advice and resting. I am looking forward to the rest of the week taking it easy being pampered by my beautiful children.
Thank you all for your wishes and thoughts.
